About VAT Calculator

Value Added Tax (VAT) is a consumption tax charged as a percentage of a price, and the single most common task is converting between a net (tax-exclusive) figure and a gross (tax-inclusive) figure. This calculator does both. In Add VAT mode it takes the net amount and multiplies by (1 + rate), so a net of 100 at 23% becomes a gross of 123, with 23 of that being VAT. In Remove VAT mode it works backwards from a VAT-inclusive total: net = gross / (1 + rate). That division is the part people most often get wrong. To strip 23% VAT from a gross of 123 you divide by 1.23 to get 100 net and 23 VAT, you do not subtract 23% of 123 (which would wrongly give 94.71). The reverse calculation always uses the rate as a fraction of the net, never of the gross.

The tool accepts any rate from 0 to 100%, with common European rates pre-set for convenience. Ireland uses a 23% standard rate, a 13.5% reduced rate (for fuel, building services, and many repairs), a 9% second reduced rate, and 0% on zero-rated supplies such as most food, children's clothing, and oral medicines. Other EU members differ: Germany applies 19% standard and 7% reduced, France 20% / 10% / 5.5%, and Portugal 23% / 13% / 6% on the mainland. There is no single "EU VAT rate", so always pick the rate that matches the country and category of the supply rather than assuming the standard rate applies.

Typical uses include pricing a quote for a client, reconciling a supplier invoice, or splitting a till receipt into its net and tax parts for bookkeeping. If you are a VAT-registered business issuing an invoice, you usually start from a net price and add VAT. If you are reading a consumer receipt or a gross quote and need the net for your accounts, you remove VAT. Two situations sit outside a simple percentage calculation: zero-rated supplies (taxable at 0%, so the gross equals the net) and exempt supplies such as certain financial and medical services, where no VAT applies at all and no input VAT can be reclaimed. The reverse-charge mechanism on many cross-border B2B sales also shifts the VAT accounting to the buyer, so the supplier shows no VAT on the invoice even though the transaction is taxable.

This is an arithmetic tool, not tax advice or a filing aid. It assumes a single rate applies to the whole amount, so a mixed basket of items at different rates must be calculated line by line. Rounding on real invoices follows specific rules (typically rounding the VAT per line or per invoice to the nearest cent), which can produce totals a cent or two off from a single bulk calculation. For registration thresholds, partial exemption, margin schemes, and what you may reclaim, check the rules of the relevant tax authority.
